I think it's just a difference between *BSD's API and the Linux one. In 
pkgsrc/libusb, the function to detach is commented out if you are on *BSD:
 	int usb_detach_kernel_driver_np(usb_dev_handle *dev, int interface);

By disabling uhidev (so the missile launcher appears as ugen) and taking 
the above into account, the Linux driver works. So I can shoot things from 
NetBSD now, but it's not an ideal way of doing it (it really is a hid 
device - it appears like that under Windows).
